Specification of Letters Patent.

Application filed. mam 9, 1920. Serial No. 357,178.

To all to how it wary concern Be it known that I, Lorenzo \V. BELL, a citizen of the United States, residing at Carrollton, in the county of Carroll and State of Missouri, have invented certain'new and useful Improvements in Attachments for Threshing-Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain in'iprovements in attachments for threshing machines and has relation more particularly to a de I vice of this general character especially designed and adapted for use in connection withthe tube of a pneumatic stacker, and it is an object of the invention to provide a novel and improved attachment of this general character which operates to recover grain which would otherwise be carried out and lost with the straw.

The invention consists in construction and in the combination and ar rangement of the several parts of my improved attachment whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will. be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings,v wherein:

Figure l is a fragmentary view in side elevation illustrating an attachment constructed in accordance with an embodiment of my invention and in applied position, said attachment being shown in substantially a closed positionwith respect to the coacting hood, a working position of the attachment being diagrammatically indicated by dotted lines.

Fig. 2 is an enlarged fragmentary sectional view taken through my improved attachment as herein disclosed detached;

Fig. 3 is a view partly in top plan and partly in section of the structure illustrated in Fig. 3; and

Fig. 4 is a transverse sectional view with portions in elevation of my improved attachment as herein embodied.

As disclosed in the accompanying drawings, C denotes a tube of a conventional type i the details of embodied in a pneumatic straw stacker of: a threshing machine and which is provided at its outer or discharging end with'a hood H, also of a conventional type. My improved attachment comprises a body or apron 1 of desired dimensions and having extending along its side margins the side members 2 to each of which is secured an outstanding wing 23. Theouter end of the bodyor apron 1 is provided with an outstanding flange extending entirely thereacross and connecting the side members 2 are the longitudinally spaced slats i disposed in cross section on predetermined inclinations. The lower margins of the slats i are spaced. from the body or apron 1 so that, in practice, an unobstructed flow of the separated grain may be had thereover.

The opposite end portion of the body or apron l is provided with an extension 5 with which is suitably engaged a return spout 6 leading to a delivery within a hopper 7 suitably sup ported adjacent the lower end oi the tube and preferably by the threshing machine proper. The lower portion of the hopper T is provided with a discharge spout 8 to which a sack S is adapted to be engaged so that said sack may be readily filled by the recovered grain.

Extending upwardly from the lower end portions of the side members 2 of the body or apron 1 is a substantially U-shaped yoke 9 having its side members a in pivotal c011- nection with a split ring 10. Coacting with the free extremities of the member or split ring 10 is a clamping bolt 11 of aconventional type.

In practice, the member or ring 10 is adapted to be clamped around the tube 0 at a point inwardly of but in close proximity to the hood H with the body or apron 1 below the hood and upon which said hood delivers, and the apron 1 is then adjusted in desired position with respect to the hood H so that the straw delivered thereon may readily pass over the slats l. As the straw is discharged through the hood H, it passes over the slats 4 whereby the grain passing out with said straw is recovered by said slats and drops upon the body or apron 1. Said recovered grain travels by, gravity into the return spout 6 and is conveyed to the hopper 7. Operatively engaged with. the

oke 9 is an outstanding lever 12 to which is secured an end portion of a flange memher 14: or the like. The member it extends downwardly. of the tube C and is engaged with the lever 15 whereby the body or apron 1 may be readily adjusted to a position relative to the hood H which best meets the requirements of practice.

From the foregoing description, it is thought to be obvious that an attachment 7 constructed in accordance with invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it willalso be obvious that my inven I t1on is susceptible oi some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in matic stacker, an apron supported by said tube upon which the tube discharges, transversely disposed slats carried by the apron and spaced thereabove, a return spout leading from the apron, and means for adj listing the apron with respect to the discharging end of the tube.

3. An attachment of the class described comprising; a member adapted to be engaged with the discharging end portion 01 the tube of a pneumatic stacker, a member in pivotal engagement with said first named member. an apron carried by said last named memher and upon which the tube of the stacker is adapted to discharge, transversely disposed slats carried by the apron and spaced thereabove, a return spout leading- :l'rom the apron, and means for rockingsaid apron.

4. In combination with the tube of a pneumatic stacker, an apron supported by ."aid tube upon-which the tube discharges. transversely disposed slats carried by the apron and spaced thereabove, a return spout leading from the apron, and a hopper into which the return spout delivers.

In testimony whereo'l l hereunto aliix my signature.
